The car, moving at a speed of 20 m / s, transported the load in 20 minutes. what work did the car do if the engine thrust is 1470 N?

With a straight-line movement of the car and a constant value of the engine thrust force, the work that the car has done can be calculated by the formula:

A = F * S, where F is the traction force of the car engine (F = 1470 N), S is the movement of the car (S = V * t, where V is the speed of the car (V = 20 m / s), t is the time of movement vehicle (t = 20 min = 1200 s)).

A = F * S = F * V * t = 1470 * 20 * 1200 = 35280000 J = 35.28 MJ.

Answer: The car performed work equal to 35.28 MJ.
